Specification of Letters Patent.

Patented June 8, 1915.

Application filed August 21, 1914. Serial No. 857,897.

cated, of a peculiar stock for properly guiding the device along the edge. of a board or other object, in combination with an arm assembled with the stock in a peculiar manner to be adjusted transversely thereof, whereby the utility of the implement is enhanced.

It is also within the scope of the invention to improve generally devices of the characterto which the present invention relates, whereby the same will be comparatively simple, compact and inexpensive in construction, as well as being serviceable, practical and efficient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a plan view of the improved implement. Fig. 2 is a side elevation thereof. Fig. 3 is a sectional view taken on the line 33 of Fig. 2, the arm being shown in full.

In carrying out the present invention, there is provided an angular stock 1 having the flanges 2 and 3 arranged at right angles with respect to one another, and adapted to engage over one corner of a board or other object, with the flange 3 resting against the edge of the board, and with the flange 2 resting upon the top or upper surface of the board. In this manner, the stock 1 is adapted to be slid in a convenient manner along the edge or side of the board.

The upper flange 2 is provided with a transverse dove-tailed groove or slot 4, through which is slidable an arm or bar 5 of dove-tailed cross section, it being noted that the arm or beam 5 may be adjusted longitudinally of itself through the grooved channel 4, but is constrained against displacement in any other direction unless the arm is withdrawn from the groove 4 to separate the stock and arm. The arm 5 is provided with a longitudinal series of graduations 6 upon its upper face, and the upper face of the flange 2 of the stock is provided with a pointer 7 cooperable with the graduations 6 for indicating the position of the arm 5 with respect to the stock.

That end of the arm 5-which projects beyond the free edge of the flange 2, is provided with an opening or aperture 8, through which a pencil or other marking element 9 is inserted, and said end of the arm 5 is provided with a slit or slot 10 extending from the opening or aperture 8, and

providing a pair of yieldable portions 11 which are engaged by a clamping screw 12, in order that when the clamping screw is tightened, the pencil or marking element 9 will be clamped within the aperture or opening 8. Thus, when the screw 12 is loosened, the marking element 9 may be removed or adjusted vertically, as desired, the distance of the marking element 9 from the inner face of the flange 3 being indicated by the pointer 7 uoon the scale of graduations 6.

In order to clamp the arm 5 at any position to which it is set, a transverse thumb piece 13 is provided upon the flange 2 adj acent the groove 4, and has a screw 14 threaded into the stock 1, whereby the ends of the thumb piece 13 are adapted to move over and engage the arm 5 when the screw 14 is tightened by rotating the thumb piece. Thus, when the thumb piece 13 is rotated, to tighten the screw 14, the ends of the thumb piece 13 are adapted to bear upon the arm or beam 5 and the stock for clamping the said arm within the groove 4, and when the screw 14 is unscrewed, the arm 5 will be released in order that it may be adjusted transversely of the stock 1.

The flanges 2 and 3 of the stock 1 are beveled at one end, as at 15, in order to provide a miter square, for marking ofl' angles upon the surfaces to which the stock 1 is applied.

The present implement or tool is particularly adapted for use in manual training, or by carpenters or similar artisans. The angular stock 1 enables the same to be readily and properly applied to the edge or side of a board, and by adjusting the arm'5 with respect to the stock, the marking element 9 may be properly adjusted from the edge of the board through the medium of the pointer 7 and the graduations 6. Then, by running the stock 1 along the edge of the board the marking element 9 will make a line upon the board parallel with and at a predetermined distance from the edge of the board. In a like manner, by readjusting the arm 5, parallel lines may be drawn upon the board, according to the work being done.

The present device may also be employed as a try-square since the arm 5 is disposed at right angles to the stock 1, and furthermore the beveled ends 15 of the flanges 2 and 3 will enable the implement to be employed as 'a bevel square, to increase the utility of the device. The other advantages and capabilities of the present invention will be obvious from the foregoing, taken in connection with the drawing, without extensive.

comment being necessary;

In order that the markingelement 9 may be set within the free edge of the relatively wide flange 2, the said flange is provided with a transverse open slot 16 below the groove or channel and extending to the flange 3 for receiving the. pointed end of the marking element when the marking element threaded into the stock and having a transverse thumb piece having its ends adapted to bear upon the arm and stock to bind the arm within the channel.

2. In a device-of the character described, an angular stock having flanges, and an arm slidably engaged to one flange of the stock and having means for carrying a marking element, the said flange of the stock being relatively wide and having an open transverse slot extending to the other flange for receiving the marking element.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two wltnesses.
